Description
Technical field
The present invention relates to a kind of complete processing of metal abrasives, be specifically related to a kind of thermal treatment process of high rigidity steel wire cut pill.
Background technology
It is several that shot blasting and strengthening metal abrasives mainly contain cast steel ball, cast iron pellets, steel wire cut pill etc.Wherein cast steel ball forms due to casting, and heart portion easily forms shrinkage cavity or the defect such as loose, and its its fatigue lifetime and cleaning effect are affected; The cast iron pellets Irving life-span too low (on average only having about 600 times), and seriously polluted, use cost is too high, on the verge of being replaced at present; And steel wire cut pill is formed by steel wire segment, it organizes very fine and close, and Irving's life-span is very long, and hardness is high, and processing speed is fast, is the desired metallic abrasive material of impeller blasting and strengthening.
But in existing production technology, ordinary steel wire pill cutting is generally without thermal treatment, namely use after cutting, rounding passivation, its hardness only has 48-55HRC, when processing the material of 60HRC and above hardness, poor effect, makes the application of steel wire cut pill be restricted.Throwing the needs of shot-peening in order to adapt to domestic high hardness material workpiece, the invention provides a kind of thermal treatment process of high rigidity steel wire cut pill.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of when steel wire cut pill ensure proper toughness, hardness is improved significantly, can carry out the thermal treatment process of the removing surface of high tensile steel plate and the high rigidity steel wire cut pill of strengthening.

In quenching Step, quenchant is water.
As a modification of the present invention, in the thermal treatment process of high rigidity steel wire cut pill:
Quench hot condition is: in 800 DEG C of-840 DEG C of temperature ranges, carry out quench treatment to the high-carbon steel wire pill cutting of CW1.0, CW1.5 two profiles number, soaking time is 15min, after hardness all reaches more than 64HRC after quenching, then carries out temper;
The condition of tempering is: be heated to 140 DEG C-180 DEG C, and insulation 15-30min, cools in atmosphere;
The condition of nitriding is: high-carbon steel wire pill cutting is placed in nitriding furnace, in nitriding furnace, pass into high pure nitrogen, passes into nitrogen after 1 hour, starts heating, within 3.5-4 hours, is warming up to 500 DEG C; Pass into ammonia when being heated to 350 DEG C, nitriding temperature is 500 DEG C ± 10 DEG C, and nitriding time is 30 hours.
Beneficial effect of the present invention is, high-carbon steel wire selected in the present invention adopts drawing, cutting technique is made, therefore homogeneity of ingredients is high, consistence is good, dense internal organization, and hardness deviation is little, particle size uniformity.
Complete processing in the present invention owing to high-carbon steel wire pill cutting successively being carried out quench, temper, therefore the high-carbon steel wire pill cutting through the process of this thermal treatment process has higher hardness, removing surface and the strengthening of high tensile steel plate can be carried out, make the range of application of steel wire cut pill more extensive.
Complete processing in the present invention is owing to carrying out Nitrizing Treatment by high-carbon steel wire pill cutting, and therefore this thermal treatment process substantially increases the wear resistance of high-carbon steel wire pill cutting, decreases percentage of damage, effectively can save use cost, meets the principle of low-loss and energy-saving.
